Answer:
Step-by-step explanation:
4/7 x + 70 cm^3 = 3/4 x Subtract 4/7 x from both sides
3/4 x - 4/7 x = 70 cm^3 The lowest common denominator is 28

5x = 70*28
5x = 1960 Divide by 5
x = 1960/5
x = 392 cc
Answer:
-18
Step-by-step explanation:
Answer:
59/ 60
Step-by-step explanation:
1.9 can be expressed as 19/10
Thus, our equation becomes
19/10 -11/12.
This becomes (228 -110) / 120
= 118 / 120
Simplify by 2 to get
59/60
2(x+2) = 60
x+2 = 30
x = 28
The correct answer is C
